In that case this is the simplest approach:

>> for st in s:
>>  if line.startswith(st):  do something

That means that if you are reading the lines from a file you'd need a 
neted loop:

for line in someFile:
   for substring in s:
      if line.startswith(substring):
         # do something here

Alternatively a regular exression match as suggested by others is
